I have a function that “capitalizes” strings, make the first letter of a word capital, the rest lower-case.

function nameize($str,$a_char = array("'","-"," ")){

//$str contains the complete raw name string

//$a_char is an array containing the characters we use as separators for capitalization. If you don't pass anything, there are three in there as default.

$string = strtolower($str);

foreach ($a_char as $temp){

$pos = strpos($string,$temp);

if ($pos){

//we are in the loop because we found one of the special characters in the array, so lets split it up into chunks and capitalize each one.

$mend = '';

$a_split = explode($temp,$string);

foreach ($a_split as $temp2){

//capitalize each portion of the string which was separated at a special character

$mend .= ucfirst($temp2).$temp;

}

$string = substr($mend,0,-1);

}

}

return ucfirst($string);

}

Where can I apply nameize() to make sure the fullname from the form is capitalized before it is entered in the database?

The fullname field, field_1, is part of a loop in register.php. Where can I apply nameize() to just the field_1 value?

A CSS solution is no good. I also want to figure out how to make a two-part name required in the fullname field.
